The plastic 'back casing' of a legit Sony Ericsson Walkman that holds the battery in.

Using the arrow sticker on the inside of the casing it could be used as a Squaid-o-meter to detect the presence of Squaids. It could also be used to detect people who were 'going sick'.
"I've found the source of Squaids!"

"How?"

"Using my Phony Ericsson Walkman, this specimen was going sick and had high levels on the squaid-o-meter!"
